AMBI-250 250 kg military & defence incinerator

The AMBI-250 takes 250 kg per charge and burns at under 50 kg/h, so the planning unit is one charge a day rather than an hourly figure. The complete cycle — first load to complete burn-down, taking in heat-up, cool-down and ash removal — runs to several hours, and the exact figure is confirmed against your own waste at commissioning. Size it on what has to be cleared per cycle.

Batch. The AMBI-250 is charged, run, and emptied as one cycle rather than fed continuously. The practical planning unit is one cycle per working day, with cool-down and ash removal before the next charge.

The AMBI-250 is specified for ammunition & ordnance waste, classified document destruction, base & field camp waste, field medical & aid post waste, uniform, insignia & id destruction and fuel, oil & contaminated absorbents. It reaches 850–1,200°C and holds flue gas above 850°C for two seconds in the secondary chamber, which is the Industrial Emissions Directive condition for these streams.

The AMBI-250 weighs 2.3 t installed; external dimensions are confirmed at quotation stage. You need clear working space around it for top loading, which usually means overhead access or a loading platform, plus a stack whose height comes out of a site-specific dispersion assessment rather than a standard figure.

Yes. Running this unit needs an environmental permit from the Environment Agency in England and Wales, SEPA in Scotland or NIEA in Northern Ireland. The waste codes for defence waste have to be named in the application, and a permit written for general waste does not silently cover them. We supply the technical data pack the permit application relies on.

The AMBI-250 runs on natural gas, hydrogen, diesel, LPG or biofuel through 2 burners. Being hydrogen-ready matters if you expect to decarbonise the site later: the unit does not need replacing when the fuel supply changes.

Thirty minutes from cold to operating temperature. From there it runs between 850°C and 1,200°C, with a 2.0-second gas retention time in the secondary chamber and a Coretex refractory lining. Control is through an IP6X-rated PLC panel.

Ash residue is 3–5% of input mass, so roughly 95% of what you load stops being a disposal cost. On a 250 kg charge that leaves about 10 kg of ash to remove — the only fraction still attracting gate fees and Landfill Tax.

Because the transfer itself is the risk. Once protectively marked material leaves the perimeter it is in someone else's chain of custody, and the establishment is relying on a certificate rather than on having watched it happen. On-site incineration removes the transfer entirely — the material is destroyed where it was generated, by staff who already hold the clearance to handle it.

Yes. These are batch units: a charge is loaded, the door is secured, and the burn runs as a discrete cycle rather than a continuous feed. That makes it straightforward to have a nominated witness present for the charge and to record the cycle against a destruction register. The ash that remains is 3–5% of input mass with no recoverable structure.

Yes. Crown status does not exempt a site from the environmental permitting regime. Burning waste requires a permit from the Environment Agency in England and Wales, SEPA in Scotland or NIEA in Northern Ireland, and the application needs the same technical data pack as any commercial operator. We supply that pack as part of the specification.
